With these objects in view my invention consists in certain details ofconstruction and arrangement of parts :.ll as will be hereinafter fullydescribed andpu rticularl y pointed out in the appended claims.

My invention will be niore readily understooi by reference to theaccompanying drawings forming a part of this spccitieation, and inwhich,

A leaf sp'ng 16 secured at.its center to the membornthe extieniitiestheof respectively einltging'corresponding ilang of said :.pwlf, is evidently adapt to ho s thelatter a nmst relative lateral movement.. Q Each of sad spools ispreferably provided with a pwfpheral longitudinally extending .slot l?.llaving their outer en s securedat the rxtrenities of each of saidslots, are iiiwardlv lmgitudinally extending rods 17 the 10 adjacentextremities of which are spaced as shown. The extremities of the ribbon15 being provided with loops 18 adapted to be engaged by said rods 17',usi clearly shown l. in Fig. T, n detachable ettcient. connectionbetween the former andthe spools 14 and 1t is evidenti made possible.Arranged upon either si( e of the ribbon 15, the saine beiner equallyspaced thereon is ii plurality 'ol' indications individually visiblethrough 11 l of the plates 6. `In

19 formed in either drawings the naines of streets or crossings passedby the car upon which the device is arranged, are shown, saidindications being. arran upon said ribbon in the order in whic i the carin traveling in one direction crosses the streets or successivelyindicated thereby. Fix to the shafts 10 and 11, the same beingpositioned thereon so as to rotate adjacent the inner surface of themember 3 are disks 20 and 20' respectively. Pivo at 21 u n the innersurfaces of the disks 20 and ane pawls 22 and 22 respectively glamcovered openings e "said pawls as shownbeing in the forms o bell crank;levers. Leaf s rings 2b exert forces upon said pawls ten ing to normallhold the same in o rative engagement wi pinions 24 and 24 fixed to theadjacent extremities of the spools 14 and 14', said pawls evidentlyserving as a means of establishing an operative connection betweenshafts 10 and 1l. and their respective spools 14 und 14'. As stated theindications upon the ribbon 15 are equally spaced thereon, hence in theoperation of the device said ribbon must needs, upon each actuation, befed an equal distance in order to suceessivel dis lay the indicationsthereon. Inlorder i etilct such feedi of the ribbon Yprovision is malewhe y, when feeding the ribbon in one direction, the one of the spools14 or 14 u n which the ribbon is being coiled sha1 be driven oroperatively connected with its shaft 10 or 11, while the other tspoolshall be loose u n its shaft whereby e pa out of the ribbon coiledthereon w' -be governedhy the demand for it as created y the drivenreceiving spool; and whenet such conditions will bereverscd when f ingthe ribbon in the other direction. With such provision in view, thedisks 20 and 20 are rovided with similar irregular cam mem rs 25 and 25'respectively rotatably mounted thereon. Said cam members sopositionedupon the disks 20 and 20', that the inoperative ends of the pawls 22 and22 rest in ent therewith as clearly shown in Fi 8, each of said camabeing of such form t at when said end portion of the pawl coactingtherewith is restf ing in engagement with the-face 26 thereof theengaging or opposite end of the pawl will be in operative position thatis w l be permitted to engage the teeth of its coacting pinion 24 or24'; and that when said cnil portion of the pawl is restii in engagementwith the face 27 thereof, e engaging end of the pawl will bc ininoperative posi-- tion. Formed at the upper and lower ends of thecasing member 3 concentricall with the axis of the shaft 11, is ailuralitv of spaced inwardly projectin' tee 28. Said teeth are soitioned a the cams 25 and 25 so fo that the corners 29 of the latter,upon .the rotation of the disks 20 and 20' will engage said teeth asclearly shown in Fig. 8. "urther said arrangement is such that uponrotation in one direction of the connecting chain 13 the cams 25 and 25will be actuated by the teeth 28 to cause one of the pawls 22 or 22 tobe positioned to cause locking of one ofthe spools 14 or 14 to its shaftand the other pawl to be positioned to etect the free movement of theother spool upon its. shaft; and that upon notation in the otherdirection of the connecting chain, the cams 25--25-wil1 be partiallyrotated by reason of the contact of the teeth 28 to a position to cause,the reversion of the results above stated. Such construction is clearlyshown in F 8. lVith such provision it is, therefore, evident that inwhatever direction the chain 13 is driven oneof the spools 14 or 14 willbe automatically released for uncoiliiig and the other locked forreceiving of the indicator ribbon.

Secured as by screws 30 to the upper epd of the casing 1at one sidethereof, is a second auxiliary substantially' cylindrical casing 31.journaled in bea rovided in the end walls of the casing 1 is a shaft 32..Fixed to said shaft adjacent the inner end wall of casinglisa rwheel88mwitha pinion 84 tix to one extremit of e shaft 10. Also fixed to saidshaft, esame beii 'tioned thereon adjacent the H a air of ratohts.wheelsl ed aving eir inner en rocking y moun upon said shaft are twoupwardly extend' rocker arms 87 and 88, the former being bi ted at itsattaclied end to receive said end of the other. A circular split leafspring 89 the ma ve extremities of which engage notches prcvided in thelowerextremitiea of the arma 87 and 88 is adapted to normally hold saidextremities of the latter in contact or in close proximity with eachother, and consequently theupper ends' thereof in divergent positions,as clearly shown in Fig. 10. Having their outer ends upon studs 41 projfrom inner aides of the arms 7 and 8 are pawls 42 and 42' respectivelCoiled com ression springs 43 arra in housings formed upon the arms7and88,en thefreeendaof the pawls 42 and 42 are apted to normally aninwardl directed force upon the latter. The paw 42 ia so positioned thatupon inward rocking of arm 37, the saine will en the ratchet 35 to causea partial rotation ereof, and the pawl 42 is so ositioned that upon theinward rocking o the arm 88 the same will engage the ratchet 36 to causethe rotation thereof in a direction o posits to -that of the rotationimparted tf tiie ratchet 85 by the pawl 42. Formed oi the inner surfaceof the casing 31 are in- Having its extremities centrally h sin si. i

.dimm 'um when' as slot 53 -squar as clearly s wardly extending curvedshield plates 45 so positioned and of such curvature as to extend inclose proximity to and to cover the end lportions of the upperperipheries of the rata, iet wheels 35 and 36, as clearly shown in' Fig.4. Said portions 45 are of such length as to be enga d by the free endsof the pawls 42 and 42 when the arms 37 and 38 are in normal outwardlyobliquely extending position, hence said portions will normally eii'ectthe disengagement of said awl from their respective ratchets 35 an 36.With such provision it is evident that the feeding of the indicatorribbon upon the spools 14 and 14 as in a manner before described may bereadily effected by the rockin actuation of the arms 37 and 38;

raversing the interior of the casing 3l,

.the saine being secured thereon by snows 46 threaded into formed uponl'ie inner surface ofthe casin v is a plate 47. Journaled in said platein a position -parallelly extendin and in vertical alinement with theshaft 32 is a shaft 48. Carried at the inner extremity of said shaft isan eccentric 49 the saine being so positioned as to traverse the path ofrotar or oscillatory movement of the ears 50 an 50 formed upon andpro'ecting from the outer longitudinal edges o the arms 37 and 38 restively, such arrangement bein clearly s own in Fig. 10. Said eccentric tereby cvidently'forms a stop to limit the extent of inward ovement ofsaid arms. Fixed to said shaft 48 at the opposite side of the plate 47is a beveled gear 51 and to the outer extremity thereof is un indicatorarm 52 the otiset outer extremit =y of which projects through a circulargraduated formed in the outer end wall of the casing 31. Loosely mountedupon the shaft 32 is a worm 54 operatively connecting which and the gear51 is a ear 55 mounted ir. a bearing 56 secured to t e plate 47, asclearly shown in Fig. 6. The outer end of said worm rojects throu h thecasing 31 and is iown in Fig. 6, to rcceive a disk 57 through tbe mediumof which said worm may evidently be rotated.

Mounted upon the squared outer end of the shaft 32 is a disk 58 held inposition thereon by a cotter pin 59. Formed upon the periphery of thedisk 48 tre outwardly extending liifurcated ears 60. ,'Ihrcaded in anoutwardly projectin ear 61 formed at the periphery of the disk 57 is athumb screw 62 the inner extremity of which is adapted to engage thebifurcations in thc ear as clearly shown in Fig. 5. lith auch provisionit is clear that said screw 6% forms a means of o ieratively connectingthe worm 54 in the sha t 32. By .auch provision, by simply unscrcwingsaid screw to discrigement with the ears 60 the shaft 32 may rotatedindependently of said worin ,und hence of the gear 51 and the eccentric49.

B521 the provision of said eccentric arranged an as shown and described,the same will automatically regulate the extent of vibration oroscillation of the arms 37 and 38 in such a manner that the length orextent of indi cater ribbon uncoiled from one spool and coiled upon theother upon each feedin thereof will be constant, in other words saieccentric isof such design as to restrictV the extent of 'vibration ofone of the arms 37 or 38 when the spool actuated thereby is carrying themajority of the ribbon, hence when said spool is of increased diameter,and at the same time to permit of the corrcspondingly greater extent ofvibration of the other arm since in such instance the spool actuatedthereby will be cai'i'yin a lesser amount or the minorit of the rib onhence will be of decreased diameter.

By the provision of the indicator arm 52 the exact position of said camrelative to the arms 37 and 38 may be readily ascertained. And by theprovision of the means for operatively connecting said cam to the mainshaft 32, namely, the disks 57 and 58 und the connectin screw 62, saidcam may be readily adjustc to correct] sition the same relative to theposition o t ie indicator.

ribbon on the spools 14 and 14.

The arms 37 and 38 project through a slot 63 formed in the upper side ofthe casing 31 and are each provided with' a projecting lug 64. By meansof cords 65 secured to said lugs and passing over and operativelyconnected with the shaft 32 around pulleys 66 mounted in housinv 67formed on the upper side of the casing 31, as clearly shown in Fig. 2,said cords when the device is arran ed in a car extending to eitherextremity of the latter, said arma 37 and 38 may be rocked by theconductor or other personage from any position in which he may be in thecar.

The operation of the device is evident. The device being arran d in acar with the indicator ribbon provi ed with the names of the streets orcrossings successively arranged thereon in the order in which the saineare crossed by the car all that is required in order to operate thedevice is to draw or pull one of the cords 65 whereu n the names of thestreets will be disp ayed so as to be visible from either side of thedevice. TVheii traveling in one direction one of the cords 65 will be orated to feed the indicator ribbon in one irection, and when travelingin the other direction the other will be operated to reversely wind saidribbon since. in traveling in the opposite direction the order inwhichthe streets are crossed is reversed.

While I have shown what I deem to bc the preferred form of my device Ido not wish to be limited thereto `urtherc might be various changesniadc in the details` of construction and arrangement. of parts withoutdeparting from the spirit of the iiiveiition coin irchended within thesco of the appende eluinis. And althouh have designed my device withspecia refeicnce to ita use as a streetindicntor in a railway carr I mayuse the same for any other purpoee to which it in applicable.
